To all whom it may cone-cm:

Be it known that 1, Lewis A. Benson, a citizen of the United States of America, and a resident of Boston, in the county of Suffolkand State of, Massachusetts, have invented certain new and useful Improvements in Buffers for Doors, of which the following is a specification.

This invention relates to cushioning devices' to revent noise resulting from the closing oii doors, and has particular reference to that type of such devices known as huliers, one device of such nature being shown in U. S. Patent No. 1,022,651, granted to me April 9, 1912.

The object ofthe present invention is to provide a device of the; character illustrated in said patent but which will be simpler and easier to make and easier to apply.

To these ends the invention consists in the improvements which I shall now proceed to describe and claim.

Uf the accompanying drawings: Figure 1 is a perspective view of a portion of an automobile body and door janib having one of my improved devices applied thereto. Fig. 2 is an elevation partly broken out or in section. of line 22 of Fig. 1.. Fig. 3 represents a section on line 3-3 of Fig. 2. Fig. 4 represents a section on line k4 of Fig. 1. Fig. 5 is a view similar to Fig. at but showing the door also, the door being closed and the buffer cushion or sliding head pushed into the casing. Fig. 6 is a perspective view of flanges.

The same references indicate the same parts in all the figures.

portion of the body of a vehicle such as an automobile is shown at 10, said body having a jamb 11 for the door 12 (Fig. 5). The face of the jalnb 11 is narrow, freguently narrower than shown inthe draw:

lugs and it is recessed or rabbeted to receive,

the casing 13 of the device, said casing being laterally narrow and vertically elongated. The casing 13 is formed or provided with flanges 14 having suitable holes for screws to secure the device in place. The casing 13 is plain in the sense that it has no ribs and consequently it may be economisally manufactured, as by casting. Slidably mounted within the casing 13 is a butler head 15 which is preferably of such material a springprojected buffer the casing and its attaching Fig. 2. These bent as vulcanized fiber. li iounted w "his the casing and between the bottom thereof and. the inner face oi. the head iii are two coiled springs 16 which normally hold the huiier cad in substantially the projected position indicated in Figs. 1, 2 and 4. To prevent the head from being ejected from the casing, and also to aid in guidingit in its sliding movements in said casing, ll provide a guide loop 17 which embraces a c. pin 18 which extends transversely of the casing shown in Figs. 2, 3, i and ii. The guide loop i'l preferably consists of a flat strip of bent to elongated U form and having its ends bent outwardly as indicated at 19 ends 19 serve to anchor the guide loop in the head 15, it being undcrstood that when the said head 15 is made of vulcanized fiber, it may be molded relatively to the guide loop, as shown in Fig. 2.

In practice the face of the door jamo is mortised or recessed for the device, the face which includes the flanges il-{l li-eing polished or plated. The buffer presents a vertically elongated cushion or head such area that,

although restricted as to width, no indenting or cracking of the door slainini against it can occur. Such vertical elong. tion results in less noise of contact than if a sn'iall round butler possessing the necessary resistance were employed. The ends of the springs 16 may be embedded or seated in shallow sockets formed in the rear face of the head 15 so as to retain the springs in their proper relative positions where they cannot inten fere with the reaward movement of the guide loop .17 when the head is pushed in as shown in Fig. 5. Said springs are of course held squealiing can result from contact with the guide loop of said springs. Owing to the'fact that the guide loop is made of a flat strip of metal the width of which is substantially equal. to the interior laterally of the casing, as. clearly shown in Big. 5, the edges of said guide loop will he guided by the inner faces of the said members of the casing 13 so as to prevent any lateral rocking or tilting of the elongated head as it slides in the casing.

1. A buii'er for a door jamh comprising a casing having a transverse guide pin, and head slidably separate from the guide loop so that no noise or 10 rearwardly extending flat loop embracing 2. A buffer for a door jamb comprising a laterally narrow and vertically elongated casing having flanges whereby the casing may be secured in place, said casing having a transverse guide pin, a buffer head slidably mounted 1n said casing and having a said guide in, and springs on opposite sides of the gui e pin and loop confined between said head and the bottom of the casing.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
